  • jpg images to gif ffmpeg no data found in image

    3 juillet 2023, par Idk123

    I was trying to use ffmpeg to create a gif from jpg images, but I wasn't able to convert them, not through a python code and not even from the dir itself in cmd

    


    running cmd in the folder :

    


    python code :

    


    input_files = f"{BASE_DIR}\\qr_images\\qr%d.jpg"
command = f'ffmpeg -i {input_files} output.gif'
os.system(f'start /wait cmd /k {command}')


    


    the dir

    


    I need the files in the dir to be able to convert to gif using ffmpeg (I have it installed correctly)

    


    this is the complete cmd dialog (if I run it from the dir in cmd or if i run the python code :

  • Cannot duplicate virtual camera on Orange Pi 5B [closed]

    21 janvier 2024, par Denis Kotov

    I have faced with the issue that I cannot duplicate virtual camera for SkyDroid 5.8GHz OTG Receiver on Orange Pi 5B :

    Also I tried to duplicate video camera using ffmpeg :

    But it also did not work ...

    


    The reason I want it, because I try to have additional processing using OpenCV but the camera is opened by another application, and it is not possible to similtuniuously open camera in 2 applications at the same time ...

    


    Have somebody faced with similar issue ?
